Solidity Simple Upgradable Proxy Contract

This example demonstrates a simplified upgradable proxy pattern written in Solidity. It is designed solely to showcase the basic mechanism of the pattern, without implementing security checks or other optimizations.

Upgradable contracts are used to overcome the limitations of immutable smart contracts on the blockchain. The proxy pattern allows us to separate the logic of a contract into a different contract, enabling upgrades to the logic contract without affecting the stored data, thus maintaining data persistence while adding new functionalities.

Test

To run the tests, use the following command:

forge test -vvv

Warning

This example is only intended to demonstrate the working principle of the upgradable proxy pattern. In real-world projects, proper security measures and validations must be applied.
